SPECIFICATION formingpart of Letters IEatent No. 592,974, dated November 2, 1897.

A licati n filed August 12, 1896. herial No. 602,529. (No model.)

To ail whom it may concern.-

Be it known that I, ALEXANDER W. PEN- muo'ron, a citizen of the United States, residing at Cleveland, in the county of Guyahoga and State'of Ohio, have invented certain new and useful Improvements in Sash-Locks, .of which the following is a specification.

This invention relates to sash-locks for windows, and has for its object to provide a ready and efficient means of locking one or both the upper and lower sash either in open position at the top and bottom for ventilation or when entirely closed, and is adapted especially for sash having counterbalanceweights.

The invention consists in the peculiar construction and combination of the parts comprising the device, substantially as hereinafter described, and pointed out in the claim.

In the accompanying drawings, Figure 1 is a vertical section, as on line 1 l on Fig. 2, through the sash, the lock, and the windowframe supporting the lock, showing the position and working relationship of the lock with the sash. Fig. 2 is a horizontal section of the same on line 2 2 on Fig. 1. Fig. 3 isa rear view of the lock with the back plate removed to show some of the interior construction, as would be seen looking in the direction of the arrows in Figs. 1 and 2.

A is abox or casing for containing the working parts of the device, which is fitted in the jamb of the window-frame at the point of the meeting-rails of the sash for adapting the lock for working with both the upper and lower sash.

B B are sliding bolts fitted to play in slots in the front wall of the box A.

b b are side wings on the bolts, having holes through which pins or rods 0 0, attached to the removable back plate 0, pass, and upon which said bolts slide in their movements.

3 s are springs on said pins or rods 0 c, which bear against the back plate 0 and the wings b b and are for forcing and holding the bolts outward.

D is a rock-shaft placed in the lower front side of the box A, a slot 0. being provided in one end wall for its insertion.

e are blocks made on the back plate Qwhich serve as retainers for keeping the shaft in place. I

cl d are arms on the shaft D, which extend upward between the wings Z? Z) on the bolts B B and the front wall of box A, and are adapted for pushing the bolts inward when the shaft is turned. The shaft extends outward from one end of the box and through the window-frame and is provided with a crank H, by which the shaft is turned from the outside.

K K are rack-bars attached to the lower part of the upper sash and to the upper part of the lower sash, and work in connection with the two bolts B B, respectively.

The working of this device is as follows: lVhen either of the sash are to be moved, the bolts are withdrawn by turning the crank. Now the upper sash may be lowered as far as required and locked in position by the return of the bolt. The lower sash maybe raised in like manner. The sash cannot be opened farther without withdrawing the bolt, but the sash may be closed, as the rack-bars push the bolts inwardly.

Having described my invention, what I claim is In a sash-lock, the combination with the casing A provided with the pins 0 c, of the bolts B 13, having the lugs b I) provided with holes and movably supported on said pins, springs s s on said pins for pressing and holdin g the bolts outward and in engagement with rack -bars K K on the window-frame, and means for pushing said bolts inward, substantially as and for the purpose specified.

ALEXANDER W. PENNINGTON.
